Purpose: The present study aimed to determine the prevalence of subjective symptoms of late complications mainly caused by radiotherapy in breast-conserving therapy (BCT), and to identify patients and treatment factors that may predict such complications.
Materials and Methods: A cross-sectional survey was conducted on 247 patients who had had early breast cancer and who were free of recurrence after BCT. Self-administered questionnaires were mailed to the 247 patients. Patient and treatment factors were analyzed.
Results: Responses were received from 193 of the 247 patients. Common perceptions of late complications included shrinking in size (85%), pain (73%), firmness (65%), thickening of the arm (34%), and changes in skin color (19%). However, high-grade toxicity (above Grade 2) was perceived in only 0.52-7.8% of patients. In multivariate models, shrinking in size was associated with age (P=0.020), pain was associated with additional boost irradiation (P=0.015), and firmness was associated with time after surgery (P=0.004).
Conclusions: Late complications as perceived by the patient herself after BCT are common, but tend to be of minimal severity. Most predictive factors are inevitably associated with late complications. However, the boost irradiation may not be indicated for every patient from a QOL perspective.
